7 MAINTENANCE
All the operations described in this chapter must always be carried out by qualified and authorised
personnel.
Before carrying out any work on the unit or accessing internal parts, make sure you have turned off
the power supply to it.
The compressors and delivery pipes are very hot. Be particularly careful when working near them.
Be particularly careful when working near the finned coils as the aluminium fins are very sharp.
Do not access moving parts without guards.
In units with capacitors and/or inverters, certain components can remain live for several minutes even
after having turned off the main switch.
Wait 10 minutes before working on the electrical parts of the unit.
Circuits supplied from external sources (made with orange cable) can remain live even after the power
supply to the unit has been turned off.
Work on the unit only if there is sufficient lighting for the type of work to be carried out.
7.1 Adjustments
All the parameters that control the operation of the unit can be set through the user interface of the control.
Refer to the control manual should modifications be necessary, but contact the manufacturer first.
Calibrations regarding the safety of the unit cannot be modified (safety valves, high pressure switches, fuses, etc.) or
are in any case protected from tampering (calibration of thermal overload protection devices, timers, etc.).
If in any case replacement becomes necessary, it is essential to use components supplied by the manufacturer (in
the case of adjustable parts) or with the same sizes and characteristics (in the case of fuses).
